To aZZ whomit nuty (2012087471,:

Be it known that I, JAMEs ALEXANDER TRANE, of La Crosse, in the county of La Crosse and State of VVisconsiu, have inventcd a new and Iinproved Stean1-Trap, of which the following is a full, clear, and exact description.

My invention consists of the escapepipe of the trap, extended nearly to the bot-tom inside, to trap the steam by the water of conclensation, and having a valve which, before the water falls to the end of the pipe, is closed by, a ficat, and reinains closed until the water rises to about two'thirds of the height of the ch'ai'nber, when it is opened by the float, to allow the water to be forced out through the waste-pipe by the steam, making' an efficient and reliable trap through which the steam 'cannot waste V when the water falls, all as hereinafter fully described. o

Reference is to he had to the accompanying d rawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of niy improved steam-trap. Fig. 2 is a transverse section taken on the line :r x' of Fig. 1, and Fig. 8 is a detail of the regulatingcock in section.

I make a strong trap-case, a, preferably of cast metal, having one removable head, b, and provided with 'legs c, for standing on the floor, said case being capable of standing boilerpressure of steam, and fit said case'with the inlet-pipe (Z and waste-pipe c for the water, said waste-pipe extending nearly to the bot tom of the case, and in this case I fit a coclr, f, or valve, which has for its stem a triangular plate, g, having a cnrved slot, h, in 4which two stop-pins, i, are fitted adjustably, so as to be shifted to set them at different distances apart. On the center j of said Valve-Stein a lever, k, of a float, Z, is pivoted, which plays between the stops 11 as the water rises and falls.

by the fall of the water, and shut off the escape through pipe e just before the water falls to the lower end of the pipe e. The other stop is to be set according to the height it is desired that the water shall rise before opening the pipe, which I prefer to be abouttwo-thirds of the height of the case.

lt will be scen that by this improve-(l apparatns the water cannot in any case be forced out, so that the steam will blow through, as it does in some other traps.

On the top of the case is an air-cock, Z, and at the bottoni a wasteicock, m, to draw off the water in cold weather when the trap is not in use.

I do not abandon or dedicate to the public any patenta-blc feature set forth herein and 'not hereinafter clainied, but rescrve the right to claim the same either in a reissue of any patent that niay be granted upon this applica tion or in other applications for Letters Patent that I may make.

Having thus described iny invcntion, what I claiin as new, and desire to secure by Letters Patent, is-- The combination, in a steam-trap, of the wastepipe e, eXtcnd-ing nearly to the bottoni of the chainber, the regulating-cockf in said pipe, and the iloat Z, the arin of said fioat acting on the cook by the adjustable stops i'of plate g, closing it before the water falls to the lower end of the pipe c, and allowin'g it to remain closed until the water rises a predctermincd distance above said end of the pipe, substantially as described.

The-lower stop 4is to be so adjusted that the fioat will close the Valve when it descends
